Simultaneous human-robot adaptation for effective skill transfer
Zamani, Mohammad Ali; Öztop, Erhan (IEEE, 2015)In this paper, we propose and implement a human-in-the loop robot skill synthesis framework that involves simultaneous adaptation of the human and the robot. In this framework, the human demonstrator learns to control the ... -
A small footprint hybrid statistical and unit selection text-to-speech synthesis system for Turkish
Güner, Ekrem; Demiroğlu, Cenk (Springer Science+Business Media, 2012)Unit selection based text-to-speech synthesis (TTS) can generate high quality speech. However, The HMM-based text-to-speech (HTS) has also advantages such as the lack of spurious errors that are observed in the unit selection ... -
A small footprint hybrid statistical/unit selection text-to-speech synthesis system for agglutinative languages
Güner, Ekrem; Demiroğlu, Cenk (IEEE, 2012)Despite its success, unit selection based text-to-speech synthesis (TTS) has has some disadvantages such as sudden discontinuities in speech that distract the listeners. The HMM-based TTS (HTS) approach has been increasingly ... -

SOBE: Source behavior estimation for subjective opinions In multiagent systems
Şensoy, Murat; Kaplan, L.; Mel, G. de; Gunes, Taha Doğan (International Foundation for Autonomous Agents and Multiagent Systems (IFAAMAS), 2016)In cooperative or hostile environments, agents communicate their subjective opinions about various phenomenon. However, sources of these opinions may not always be competent and honest but more likely erroneous or even ... -
Source behavior discovery for fusion of subjective opinions
Şensoy, Murat; Kaplan, L.; Mel, G. de; Gunes, Taha (IEEE, 2016)Information is at the center of decision making in many systems and use-cases. In cooperative or hostile environments, agents communicate their subjective opinions about various phenomenon. However, sources of these opinions ... -
Spectrum-based fault localization for diagnosing concurrency faults
Koca, Feyzullah; Sözer, Hasan; Abreu, R. (Springer Science+Business Media, 2013)Concurrency faults are activated by specific thread interleavings at runtime. Traditional fault localization techniques and static analysis fall short to diagnose these faults efficiently. Existing dynamic fault-localization ... -
Streaming multicast video over software-defined networks
Noghani, Kyoomars Alizadeh; Sunay, Mehmet Oğuz (IEEE, 2014)Many of the video streaming applications in today's Internet involve the distribution of content from a CDN source to a large population of interested clients. However, widespread support of IP multicast is unavailable due ... -
Successive refinement of models for model-based testing to increase system test effectiveness
Sahin Gebizli, C.; Sözer, Hasan; Ercan, Ali Özer (IEEE, 2016)Model-based testing is used for automatically generating test cases based on models of the system under test. The effectiveness of tests depends on the contents of these models. Therefore, we introduce a novel three-step ... -
Synergistic human-robot shared control via human goal estimation
Amirshirzad, Negin; Kaya, Osman; Öztop, Erhan (IEEE, 2016)In this paper, we propose and implement a synergistic human-robot collaboration framework, where the robotic system estimates the intent or goal of the human operator while being controlled by the human in real-time. Having ... -
